Major League Baseball announced Monday it has suspended New York Yankees superstar Alex Rodriguez through the end of the 2014 season for buying performance-enhancing drugs from the now-closed Biogenesis clinic.

The three-time Amiercan League MVP has said he will appeal the suspension, and it is possible he will play in tonight's game against the Chicago White Sox at U.S. Cellular Field. Rodriguez hasn't played a major league game in 2013 following offseason hip surgery. He has been rehabbing in the minor leagues.

At issue is the defunct Biogenesis anti-aging clinic in Miami, which MLB says provided PEDs to the players.

Some players who had been linked to Biogenesis, including 2012 All-Star game MVP Melky Cabrera, 2005 AL Cy Young Award winner Bartolo Colon and San Diego Padres C Yasmani Grandal, were not suspended because they already served 50-game suspensions for positive PED tests.

Two other players named in the Biogenesis documents, Gio Gonzalez of the Washington Nationals and Danny Valencia of the Baltimore Orioles, were cleared of having violated MLB's PED rules.

Milwaukee outfielder Ryan Braun, the 2011 National League MVP, agreed two weeks ago to a 65-game suspension for violating baseball's rules on drug use after being connected to Biogenesis.
